Retrieve history events for a given entity type using Point-In-Time (PIT) search. Suitable for paginated access to large result sets.

Use the 'count' parameter in the initial request to specify how many results to return.
In subsequent requests, use both 'scrollId' (returned from the previous response) and 'count' parameters together.

Note: A new scrollId is returned with each response and must be used in the next request. Always update the scroll in your pagination logic.
